23. "Last Kiss" (2010)
Toward the end of Speak Now, when you're already wrung out from sad songs and begging for mercy, this six-minute quasi-doo-wop ballad creeps up on you to inflict more punishment. One of those flawless Nathan Chapman productions – so sparse, so delicate, flattering every tremor of her voice.
Best line: "I'm not much for dancing, but for you I did."
